A federal official familiar with the Target security breach said there is no connection between the massive account information theft and the arrests of two Mexican citizens caught with nearly 100 fraudulent credit cards.

The police chief in the South Texas city of McAllen, Victor Rodriguez, said the pair bought tens of thousands of dollars' worth of merchandise this month.

Rodriguez said he had suspected a connection between the cases.

Mary Carmen García, 27, and Daniel Guardiola Dominguez, 28, both of Monterrey, Mexico, according to Rodriguez, used cards containing the account information of South Texas residents to purchase numerous items at national retailers in the area including Best Buy, Wal-Mart and Toys R Us.

"They're obviously selling the data sets by region," Rodriguez said.

Late Monday, a federal official with knowledge of the case said there currently was no connection between the McAllen case and any ongoing investigation into the Target breach, but would not elaborate. The official spoke on condition of anonymity because the official was prohibited from providing details about the investigation.

The discrepancy could not immediately be rectified late Monday. Messages left for Rodriguez and his lieutenant Monday evening seeking a response to those comments weren't immediately returned.

Garcia and Guardiola were both being held Monday on state fraud charges. It was not immediately known whether they had retained lawyers.

Rodriguez said he did not know whether these arrests were the first related to the Target breach.

Asked about the McAllen arrests, Target spokeswoman Molly Snyder said in an email Monday that the investigation was active and ongoing.

"I'd have to refer you to local law enforcement there for any questions about their community," she said. The Minneapolis-based company said last week that it has stopped more than a dozen operations that sought to scam breach victims by way of email, phone calls and text messages.
